<p>Hi!<br>
I see that <a href="https://rust-lang.github.io/rfcs/2094-nll.html">get_default in Problem case #3</a> still doesn't work in the current version of Rust.<br>
NLL has tackled to solve this kind of problem related to named lifetimes since 2017 (e.g. <a href="https://github.com/nikomatsakis/borrowck/issues/12">borrowck Issue #12</a>), but I can't find recent updates on this.<br>
Any ideas...?</p>

<p>Problem case <a href="https://github.com/rust-lang/rust/issues/3">#3</a> is expected to be handled as part of a transition to Polonius</p>
